.ir a gz hamama Be it known that I, H RY JAMns mdaroN, "a British subject, v residing at 501 lfhoeiiix Building, Baltimore, 7 Maryland, flhave invented anew and useful Process of Preserving Wood from Decay and Fire.

My. invention relates to the protection of wootl'from the destructive actionof;weather exposure or from the humus of theground and from fire. I' attain this object by first submerging the Wood in" a strong solution which time it is" sufficiently impregnated .to destroy the sap and cellulin matter of. the

wood pores. The above initial treatment may be applied as soon as the wood iscut', but in that' ca'se allowance must be 'fnade 1 for the water it contains and salt allowed for in proportion. After the saline liquid has been drawn off, the wood is to be slowly fillmg upfthe end pores of the wood and and thoroughly dried arid kept *protecte from the weather until required for further treatment.

To

expedite the drying of the wood I app y v Specification of Letters new. Application filed- November 14,1912. serial racemes.

the above factors" to any parts requiring their" aid for drying. This mixture may b'e-either applied, with a brush or'troweled'with pressure, or merely dusted .on a's'required. v

The advantages of my. process are reduc- 'tion in cost of materialsand outfit, its ap-' plication at any time after cutting andthe very small amount of .plant required, and

the latter can readily and cheaply be movedfrom one pointto another, also that the wood impregnated as described is incombustible,

I claim:

applying with a brush a mixture of waste gas-house lime and fine ashes in equal parts and coal tar to its entiresurface, and finally any shakes or rents with aplastic mixtureof the last named ingredients.

the exuding fireproofiflg salt unite to give a protective coating.

3. The idescribed process of rendering wood incombustible which consists in impregnating it with a strong hot, 'solutionof.
